Upper clouds, and directions, for years 1902-4 (inclusive), as made at Kai- 

 koura, Marlborough, New Zealand; situated ten miles south of 

 Kaikoura Ranges, the altitude of which is 8,000 ft. Latitude. 42° 

 26' 30" S. ; longitude, 173° 4.V E. : height above sea-level. 50ft. ; 

 distance from sea, quarter of a mile. 



Records of upper-cloud (cirrus, cirro- 

 stratus, and cirro-cumulus) movement, which 

 I have kept for ten years, although the three 

 years L902 4 have only so far been collated. 

 During these three years, out of 224 obser- 

 vations the drift of cloud was from south- west 

 on eighty-seven occasions, from north-west on 

 sixty-two occasions, from west on sixty occa- 

 sions, from south on nine occasions, from south- 

 east on three occasions, from northeast on 

 two occasions, from north on one occasion, and 

 from east on no occasions. This almost in- 

 variable drift from the westward shows that 

 to be the general motion of the higher atmos- 

 pheric currents. They arc. 1 consider, the anti- 

 trades.
